centos 6.6 server

Hello,

I sucessfully installed python in my KVM CentOS 6.6 server and downloaded and installed BleachBit1.6-1.1. Below you can see the steps I performed. However, when I try to run BleachBit it will not do it and display the error message "RuntimeError: could not open display". Any advice on how to solve this is welcome!

Thanks
